Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741572, here are decompositions:

101 + 8741471 = 8741572
113 + 8741459 = 8741572
179 + 8741393 = 8741572
251 + 8741321 = 8741572
263 + 8741309 = 8741572
269 + 8741303 = 8741572
293 + 8741279 = 8741572
419 + 8741153 = 8741572

Showing the first eight; more decompositions exist.
